In this research was studied gathering efficiency and breakthrough of flask dust particles in industrial plants. The experiments were carried out on devices with counter swirling flows with various modifications and diameters of 150, 400, 600, and 800 mm. Analyzed and graphically presented the dependences of particle breakthrough on tghe devices size. The breakthrough effect in small inertial VZP devices was investigated, also the construction of VZP device was designed and experimentaly tested under operating conditions in terms of productivity and energy losses close to standard devices, but excluding the breakthrough effect of larger particles. Recommendations are given for the device usage on counter swirling flows with the best characteristics for capturing flask dust particles.
The work considers the breakthrough effect of large particles in a small diameter device on counter-swirling flows. The dependences of particle breakthrough on different diameter devices were built. An experiment was carried out on a device of 100, 200, 300 and 400 mm with top paddle strikers installed at the axial outlet. A comparative analysis is made with the calculated and experimental data of the researchers in this area. The results of devices with small diameter are obtained and presented in the visual graphs and conclusions.
The article considers the level of air pollution in several zones of the roadside territory in the city of Gudauta. Four zones are selected: roadside, residential, resort and industrial. Chemical analysis of dust samples of each zone was carried out. Comparative chemical analysis was performed between all samples. The chemical background characteristic for each zone was revealed. The dispersed analysis of the selected dust in each zone was carried out and analyzed..
The dust dispersed composition in various types of hard and soft works is under study. The dust emissions indoors concentration data is obtained. The dust concentration on distance dependence is constructed. The impact assessment of hard and soft works in warehouses and residential premises on environmental pollution by dust emissions is given. The concentration and ratio of PM2.5 to PM10 particles were calculated in order to determine the dustiness and the negative impact on the environment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
